Add BPM firmware update procedure
Adds the necessary code to update the firmware data of the BPM. This
commit doesn't support the config data portion of the update. The BPM
code hasn't been hooked into the existing NVDIMM code yet either. These
things, along with error paths, will be added in future commits.
